TRANSFERRING OR TURNING-OVER MACHINE.

SPECIFICATION forming part of Letters Patent No. 637,586, dated November 21, 1899.

Application led January 31, 1898. Serial No. 668.586. (No model.)

To all whom' it may concern.-

Beit known that I, EDWARD HETT, a citizen of the United States, and a resident of New- York, (New Dorp,) in the county of Richmond, State of New York, haveinvented certain new and useful Improvements in Transferring or Turning-Over Machines, of Which the following is a specification.

This invention relates to a transfer or turning-over machine designed to be employed in the art of lithographie or planographic transferring of a design to a printing-surface.

It also relates to certain devices associated with or forming part of such machine, but which may also be employed in other machines-such asrolling-up machines, lithographic or planographic, or other machines Working with or upon a printing surface. The purpose of the said devices is to facilitate the handling of the form or printing-surface in removing it from and depositing it into its place in such machine.

The invention consists of the structure and the various combinations of elements hereinafter pointed out.

The accompanying drawings, forming part of this specification and in which like reference-letters designate similar parts, illustrate one embodiment of the invent-ion in connection with aplanographic or lithographie transfer or turning-over machine'.

A Figure lis a side elevation of a plan ographic or lithographie transfer or turning-over machine embodying part of the invention. Fig. 2 is a central vertical sectional elevation of the same. Fig. 3 is a plan view of a transfer or turning-over machine and a receiving and transporting apparatus located in proper relation to a lithographie rolling-up machine and embodying the invention, and Fig. Liis a side elevation of the receiving and transporting apparatus.

A is the frame of the transfer or turningover machine,carrying a reciprocating bed B, driven bya screw B', geared therewith. The screw B carries a gear-wheel B2, meshing with a pinion c, loose on the shaft C, which carries a driving gear-Wheel C', adapted to be driven in either direction by a suitable motor. The pinion c is made fast on the shaft C by means of the clutch G2 and clutch-lever C3. The bed Bis provided with a rack b, for

setting-up plate on the bed.

in, whereby the printing-surface may be brought into contact with the bed B or the setting-up plate G, carried thereby, and may also be separated slightly therefrom, as shown in Fig. 2. The shaft E carries a gear-wheel D', adapted to mesh with the rack b, so that when the bed is driven the printing-surface F may be thereby rotated in contact with the In the present embodiment of theinvention these bearingboxes are supported by the pressure-arms H, Working in guides I-I, which are secured to the sides of the frame A, and the arms H are pivotally connected at their lower ends to the eccentric-arms H2, which are operated by eccentrics I', carried on the rock-shaft I, Worked by the lever I2. Then the lever u121s lifted, as shown in Figs. l and 2, the pressurearms H raise the bearing-boxes D and separate the printing-surface E from the bed, at the same time throwing the wheel D out of gear with the rack Z9 and enabling the tubular printing-surface 'E to be rotated or the bed B moved without either operating the other. When the lever is depressed,the arms H and bearing-boxes D are moved down, so as to bring the wheel D and rackh into gear and the printing-surface and setting-up plate into contact, which may be made as firm as required by suitable pressure on the lever I2.

The means described for operatingthe arms H are those preferred 5 but it should beunderstood that other means for this purpose may be employed without departing,r from my invention. In order to limit the upward-movement of the arms H, suitable 'stops are-provided. As shown in the accompanying drawings, these stops consistof collars t,'vadjust able by means of set-screws h2 and carriedby the arms I-I beneath the guides H', so as to strike against the guides when the arms have been elevated to the predetermined height. In order to sustain the arms H and bearing- Ico v estese boXes D in elevated position and prevent their return movement until desired, suitable holding devices are provided. These generally consist of eccentricallypivoted buttons or pieces h' on the arms H above the guides H', whereby when the arms have been elevated the pieces h' drop down upon the tops `of the guides and sustain the bearing-boxes in elevated position. Other means of course than the collars 7i and pieces 7L may be employed to accomplish their purposes Without departing from the invention.

The transfer or turning-over machine described is designed to be generally employed simply for the purpose of transferring or turning over lithographie transfers from the setting-up plate to the rounded or tubular printing-surface F. When a set of transfers has been turned over onto a printing-surface, that printing-surface is removed from the machine and another is put in its place to receive another set of transfers, the first surface being carried away to be prepared or developed into the character of printing-surface required, Whether planographic, relief, or intaglio. This may generallybe done in arolling-up machine whose sole function is to roll up and prepare the surface for printing. In order that the printing surfaces may be quickly handled in mounting them in and unmounting them from their working position in the transfer or turning-over machine nor other machine in which removable printingsurfacesare employed or manipulated, I provide means supported on the frame of such machine for this purpose, and I also provide an arm generally carried on a stand arranged to receive a rounded or tubular printing-surface from the turning-over machine and to carry it, if need be, to a rolling-up machine, this stand alsobeing employed to support the printing-surface, so that it may be easily shifted to its place in the transfer or turningover or other machine. I will now describe these means for handling the printing-surface.

K are lifting-arms having bifurcations at their upper end and carried by the frame A of the machine, so as to be vertically movable. One of these arms K has its upper end 7s' jointed, for a purpose to be presently described. The means best adapted for operating these lifting-arms consist of slideways K', in which the arms move, and screws L, supported by the frame and passing through threaded collars L', fast on the arms K. When y, the screws turn, the arms are driven up or f down, according to the direction of rotation.

The screwsare generally geared with a shaft M, as by means of the beveled gear-wheels l and Z', and the shaft M is preferably geared with the drivingwheel C' through a suitable train lof gearing, as the gear-wheel m on the shaft M, beveled gear-wheels m' and m2 on the shaft M', beveled gear-wheels n and a' on shaft N, and beveled gear-wheel c', loose on the driving-shaft C and arranged to be'y l locked thereon by the clutch C2 and clutchlever C3. By operating this lever C3 the main driving-wheel 0' may be thrown into gear with the screw B', so as to drive the bed B, and when the printing-surface F is lowered, with its gear-wheel D' in mesh with the rack b, the bed drives the printing-surface, which at this time is in contact with the bed or the setting-up plate carried thereby. When the clutch-lever C3 is reversed, the bed is thrown out of gear and the beveled gear c' is made fast on the shaft C, so as to gear up the drivewheel C' with the shaft M, through the train of gearing above described, and operate the screws L to raise or lower the armsK, whereby the printing-tube may be raised from or lowered into its working position, so as to be easily shifted from or to the shaft E. In removing a tube F from its working position the bearing-boxes D are first disconnected from the pressure-arms II, and the lifting-arms K are then raised so as to liftthe shaft D and tube F above the frame A to permit the tube to be slipped from the shaft. When the tube is slipped from the shaft, it is slipped onto an arm of the stand above referred to and now to be described.

The stand in its preferred construction comprises a standard O, fixed in a suitable base O', which is generally bolted to the iioor near the frame A. The standard O carries a rotatable head P, provided with one or more arms P', adapted to support a rounded or tubular printing-surface F. 'Ihe stand is solocated that the arlns P' may be brought into alinement with the shaft E when the shaft is lifted by its lifting-arms K to remove the tube F. Before the tube may be slipped from its shaft E, however, the bearing-box D opposite the stand must be slipped from the end of the shaft E and the arm -K opposite the stand must be moved out of the way, and this requires the provision of some other suitable support to hold the shaft in fixed alinement with the arm P' about to receive the tube F. To get the arm K out of the way, I joint its upper bifurcated end lo' to the main portion of the arm, so that this jointed end may be turned down below the shaft E and tube F out of the Way, this end of the shaft being rst supported by other suitable'lneans. The best supporting means for this purpose now known to me is the arm P', whose outer end is arranged to couple with the end of the shaft E by means of suitable devices, such as a bolt p, carried by the arm P and arranged to slide into a recess p in the end of the shaft E. It will thus be seen that the arm P' and shaft E form practically a single continuous shaft supported at its ends by one arm K and the standard O, along which the tube F may be quickly slipped from the shaft E to the arm P'. After this has been done the arm and shaft are then uncoupled and the arm and tube revolved on the standard, and, if

IOO

IIO

eer/,tee 3 desired, thetube is then slipped from the arm P onto a shaft of another machine-as, for instance, a rolling-up machine R.

The shaft r of the rolling-up machine,which receives the printing-surface F, is arranged to couple with the arm P in the same way as thel shaft E couples with the arm P'.

While I have shown part of my handling devices as embodied in a transfer or turningover machine, I do not wish to be understood as limiting the invention to the use of these devices in such a machine only, inasmuch as they may also be embodied in other machines wherein a printing-surface is manipulated preparatory to using it to carry on its printing function-as, for example, a rolling-up machine-or in which a printing-surface is used -to carry on its printing function.

It-is to be observed that the arms K K or other means for moving the carrier for the printing-surface to and from its working position in the machine may be arranged so as to work in any convenient manner or in any desired direction and that the arms may be variously arranged without departing from my invention, so that one may be got out of the way of the printing-surface while the printing-surface is being withdrawn from or mounted on its carrier.
